The present invention relates to a combustion apparatus for burning a gas fuel, and in particular, but not intended to be limited thereto, but relates to an anti-off gas lighter for igniting cigarettes.

For example, a general gas lighter may be a fuel tank including a fuel discharge nozzle, an ignition device (a high-pressure discharge device or a lighter ignition mechanism for performing gas ignition), and a fuel discharge nozzle driven up or down, and then, or Before that, an operating mechanism for igniting the ignition device is provided.

Conventionally, the ignition flame rises from the flame hole of the outer case (or inner case) of the lighter (in the state of use which exposes the nozzle itself, there is no flame hole: in this case, the front end opening of the nozzle).

Since the gas flow rate is relatively low, the rising strength of the flame is relatively weak, and when the wind blows, the flame goes out as soon as the fire is caught.

Thus, in the related art, the side circumference of the flame is surrounded by a cylindrical body or the like so as to reduce the direct impact of the wind on the flame (off prevention lighter).

In this anti-off gas lighter, the cylinder surrounds the outer circumference of the flame to prevent the wind, because it is necessary to supply air to the fuel gas emitted from the nozzle and to touch the spark or the ignition flame of the lighters. There is a problem that an air supply or an ignition flame hole must be formed in the sieve, which reduces the windscreen effect.

In addition, since there is a cylindrical body for the windshield, the cleaner around the nozzle is difficult and the water-retaining property is low.

Moreover, in the spark ignition type, there is a problem that the arrangement of the discharge electrodes is difficult, and complicated elements are required for mounting of the discharge electrodes and wiring of the feed line to the discharge electrodes.

An object of the present invention is to provide a gas combustion apparatus having high water retention.

In order to achieve the above object, the anti-off gas combustion device of the present invention, through the hollow insulator having an outer flange protruding outward from the central axis, and an inner flange protruding in the direction toward the central axis, the bottom A support cylinder having an inner flange abutting the underside of the outer flange of the insulator cylinder, the inner flange supporting the insulator cylinder, surrounding the upper side thereof, having an opening at the top, and having a female thread on the inner circumferential surface thereof; In the outer circumferential surface there is a male screw screwed to the female thread, the lower end is in contact with the upper surface of the outer flange passing through the insulator, the holding ring is received, the lower end is in contact with the upper end of the fixing ring, the center opening And a catalyst support ring for holding a catalyst wire in the support cylinder and screwed into the female thread of the support cylinder. A male thread on its outer circumferential surface, the lower end of which is in contact with the upper end of the catalyst support ring, the upper part of which is coupled to the inner space of the lower part of the insulator cylinder, and the air intakes from the lower side of the insulator cylinder to the lower side; And a gas mixing pipe having a fuel gas receiving port at a lower portion thereof, and having an internal space communicating with these air intake ports and a fuel gas receiving port, and an internal space communicating with an internal space of the gas mixing pipe.

EXAMPLE

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 3.

1 is an exploded perspective view of an embodiment of the present invention.

The fuel tank 20 is attached to the fuel tank 17. In this embodiment, the gas discharge valve is opened in the fuel tank 17 by pulling up the fuel nozzle 20 upwards, whereby the fuel tank ( The fuel in 17 vaporizes and emerges from the nozzle 20.

The fuel tank 17 is made of a transparent synthetic resin, and the remaining amount of the liquefied fuel therein is visible from the outside of the tank.

The fuel tank 17 is integrally formed with a side stand 19 for guiding the high pressure generator 24 and a support stand 18 for supporting the burner unit.

The high-pressure generator 24 is called a piezoelectric unit, which has a piezoelectric element that generates a high voltage by hitting and a mechanism that strikes it. The piezoelectric element is housed in an insulator body case 24c, One end is supported by a metal base 24h.

The high pressure lead 24h is connected to the other end of the piezoelectric element. The front end of the high voltage lead 24h is peeled off the insulating coating, and the conductive wire is exposed and wound around the coil 24w having a predetermined radius.

An operating case 24i is attached to the main body case 24c, and a coil spring for impact and a plunger are housed in the operating case 24i.

The outer surface of the head of the operating case 24i is exposed to a coating layer which is at the same potential as that of the base 24f.

When the operating case 24i is pushed down, the coil spring is compressed and the plunger is released to a certain position so that the plunger is driven by the spring repulsive force to hit the piezoelectric element.

At this time, the piezoelectric element generates a high voltage between the base band 24f and the operation case 24i (commonly referred to as earth) and the coil 24w (commonly referred to as high voltage electrode).

When assembling the lighter, the support plate 22 and the rubber plate 23 are inserted into the holes 17r of the fuel tank 17.

Subsequently, the operating member 21 is passed through the support base 18 between the two legs 21f ₁ and 21f ₂ , and the engaging groove 1r is connected to the flange 20f of the nozzle 20. sandwiched down, it is attached to the alignment groove the supporting foot (18) in the form of a walk (18r) of the projections (21p ₂₎ of the support foot private use (18).

The leg sleeve 5s of the mixing tube 5 is passed through the coil 24w of the piezoelectric unit 24, and the hole plate 10 and the washer 11 are formed in the leg sleeve 5s of the mixing tube 5. And inserting the filter 12 in this order, screwing and tightening the male screw of the outer circumference of the front end of the flange tube 13 to the female screw in the leg sleeve 5s, and fixed to the lower portion of the flange tube 13. The fitted elastic resin tube 15 is inserted into the rubber 0 ring 16.

Subsequently, the operation member 25 formed by pressing the metal plate is covered with the operation case 24i of the piezoelectric unit 24, and the support arm 1, the operation member 25, fixedly mounted to the support cylinder 2, and the like. With the piezoelectric unit 24 as a set, the base 24f of the piezoelectric unit 24 is inserted into the hole 17r of the fuel tank 17, and the lower leg 1f of the support arm 1 and the operation member (25) and the piezoelectric unit (24) are inserted between the support base (18) and the side stand (19) of the fuel tank (17).

With this configuration, abuts from the top of the bridge (25f _1), (25 ₂₎ of the operating member projection on the half-round by the press operation spanking of (25) (25f _1), a (25, ₂₎ the operating member (21) .

The hole 1h of the support arm 1 is aligned and aligned with the hole 18f of the support base 18.

In this state, when the operation member 25 is temporarily lowered, the operation case 24i of the piezoelectric unit 24 is pressed down, and the operation member 21 is a projection 21p ₂ (support 18). Is supported by the groove 18r of the cylinder], and rotates clockwise to raise the nozzle 20 upward (emission of fuel gas from the nozzle 20).

Subsequently, the lower end opening of the stretchable synthetic resin tube 15 is covered by the nozzle 20 and inserted into the flanger 20f, and the zero ring 16 is lowered near the flange 20f of the nozzle 20. .

As a result, the 0 ring 16 tightens the lower end of the stretchable synthetic resin tube 15 with respect to the circumferential surface of the nozzle 20.

As mentioned above, the operation member 21, the support arm 1, the operation member 25, and the piezoelectric unit 24 are squeezed to the fuel tank 17, and these are attached to the lighter case 26, and the lower opening ( It inserts from 26b), and it pushes out so that the hole 18h of the support base 18 may go upward rather than the upper opening 26h of the lighter case 26.

Then, the leg members 28f ₁ and 28f ₂ fixed and fixed to the upper cover 28 are placed over the support 18, and the holes 28h ₁ and 28h ₂ are supported by the support arms (28h ₂ ). Align and align with the holes 1h of 1) and the holes 18h of the support base 18, and insert the pins 29 into these holes to fit the upper cap 28c of the upper cover 28 to the lighter case 26. To the side.

When the upper cap 28c covers the upper opening 26h of the lighter case 26 securely, the end portions protruding in the triangular shape of the leg members 28f ₁ and 28f ₂ of the top cover 28 in this state. And the upper ends of the semicircular projections 26r ₁ and 26r ₂ of the operation member 25 by the press slap operation.

Next, the claw member 30 made of an elastic material is inserted into the lower opening 26b of the lighter case 26, and the projection 30p of the claw member 30 is inserted into the groove 26r of the lighter case 26. The lower opening 26b is covered with the lower cover 31, and the screw 32 is placed under the fuel tank through the holes 31h of the lower cover 31 and the holes 30h of the claw member 30. Screw it into the bottom screw hole.

As described above, the lighter is assembled.

When the lighter thus assembled is used, the upper cap 28c of the upper lid 28 is rotated clockwise about the pin 29 with the thumb.

Then, the leg members 28f ₁ and 28f ₂ of the top cover 28 drive 28r ₁ and 28r ₂ of the operation member 25 downward.

As the operation member 25 moves downward, the operation case 24i of the piezoelectric unit 24 is driven downward, the coil spring therein is compressed, and the operation member 21 rotates in the clockwise direction. Pull up the nozzle 20.

As a result, the fuel gas is discharged from the nozzle 20, and the released fuel gas is the elastic (elastic) synthetic resin tube 15, the filter 12, the center hole of the washer 11 and the hole plate. It enters into the mixing pipe 5 through the hole 10h (2nd FIG., 3rd FIG.) Of the center of 10, and advances upwards.

As the fuel gas flows, air is sucked into the mixing tube 5 from the air intake port 5h (2nd, 3rd degree) opened on the circumferential surface of the mixing tube 5, and the air is mixed with the fuel gas. The mixed gas enters the ignition nozzle 4 (FIGS. 2, 3) from the mixing pipe 5, enters the internal space of the support cylinder 2 from the ignition nozzle opening 4h, and the catalyst wire 7 is removed. Through this, it goes out of the support cylinder 2.

When the top cover 28 is further rotated, the plunger in the operating case 24i of the piezoelectric unit 24 is released, and when the plunger strikes the piezoelectric element by the repulsive force of the coil spring, the high voltage leads 24h. Is applied from the coil 24w to the ignition nozzle 4 (2nd, 3rd degree) in the support cylinder 2 through the mixing pipe 5, and the conduction of the operating case 24i of the piezoelectric unit 24 is applied. The fixing ring 6 (2nd, 3rd degree) is connected to the other electrode (device earth) of the piezoelectric unit 24 through the layer, the operation member 25, the support arm 1, and the support cylinder 2, As a result, a discharge spark occurs between the ignition nozzle 4 and the stationary ring 6.

By this discharge spark, the mixed gas in the support cylinder 2 is ignited, and a spark is generated, and the catalyst wire 7 is heated and heated by this spark, and it burns and accelerates | stimulates combustion of a mixed gas.

In this state, if the front end of the cigarette approaches the catalyst wire 7 above, it will catch fire.

In FIG. 2, the internal structure of the support cylinder 2 is expanded, and FIG. 3 has shown the III-III cross section.

In addition, these figures show the state just before joining the stretchable synthetic resin tube 15 to the nozzle 20.

Referring to Figs. 2 and 3, the structure of the circumference of the support cylinder 2 will be described. The metal (conductive) support cylinder 2 has a relatively thick inner flange at the lower end thereof, The lower part of the flange is a substantially cylindrical shape in which a small diameter thin sleeve is integrated, and an internal thread 2s is dug in the inner wall surface.

This support cylinder 2 attaches a thin sleeve of the said small diameter to the outside through the hole of the front end of the ring shape of the support arm 1 of metal (conductive) by attaching a thin sleeve to the outside. It is fixedly attached to the support arm 1.

The ceramic (insulator) cylinder 3 is inserted into the hole of the inner flange of the support cylinder 2 from above.

The ceramic cylinder 3 is a shape which has an outer flange at the upper end and an inner flange at the center, and the lower surface of the outer flange abuts on the upper surface of the flange of the support cylinder 2.

The metal (conductive) retaining ring 6 has an inner flange at the lower end, a male screw on the outer circumferential surface, and a recess 6s (third) into which the front end of the negative driver (screwdriver) enters the upper end surface (third). Degrees).

By screwing the fixing ring 6 into the supporting cylinder 2, the upper end surface of the ceramic cylinder 3 is pressed down by the fixing ring 6, and finally, the inner flange of the supporting cylinder 2 The outer flange of the ceramic cylinder 3 is fastened to the inner flange of the fixing ring 6, whereby the ceramic cylinder 3 is fixedly mounted to the support cylinder 2.

The metal (conductive) ignition nozzle 4 is inserted into the center hole of the inner flange of the ceramic cylinder 3, and the front end of the metal (conductive) mixing tube 5 is inserted into the lower opening of the cylinder 3. Is inserted into the female thread formed on the inner circumferential surface of the mixing tube 5, and the male screw formed on the outer circumferential surface of the lower part of the nozzle 4 is screwed into the mixing tube 5 in the ignition nozzle 4. Both of these are fixedly mounted, and both of them are fixedly mounted to the ceramic cylinder 3 in such a manner that the inner flange of the ceramic cylinder 3 is tightened.

In the support cylinder 2, the catalyst support ring 8 which supports the catalyst wire 7 is inserted in the center part from the opening of the upper end part, and is supported by the fixed ring 6. As shown in FIG.

The pressing ring 9, which has a hexagonal hole 9h corresponding to the outer shape of the hexagon nut at the upper end, has a male screw on the outer circumferential surface, and the male screw 2s on the inner circumferential surface of the support cylinder 2 is provided. And screwing in.

By inserting and turning a hexagonal screwdriver into the hexagon hole 9h, the pressing ring 9 is screwed into the supporting cylinder 2, and the catalyst support ring 8 is fitted with the pressing ring 9 and the fixing ring. It is tightened with (6).

The fixing ring 6 is electrically connected to the support arm 1 through the support cylinder 2, and the support arm 1 is operated via the operating member 25 to operate the case 24i of the piezoelectric unit 24. Since it is electrically connected to the conductive layer (device earth electrode), the fixed ring 6 has a function as one discharge electrode (device earth) connected to the piezoelectric unit 24.

The coil 24w at the front end of the high pressure lead 24h of the piezoelectric unit 24 peels off the insulation of the high pressure lead 24h, and the core wire (conductor) is separated from the leg sleeve 5s of the mixing pipe 5. It was wound to a diameter slightly smaller than the outer diameter of, and the leg sleeve 5s is fitted into the coil 24w and pressed by the toothed flange 5f for the screw projection of the mixing pipe 5.

As a result, the ignition nozzle 4 is electrically connected to the high pressure lead 24h of the piezoelectric unit 24 via the mixing pipe 5. (In addition, even if there is a slight gap, when a high voltage is applied, the gap is discharged and conducts.)

The front end of the ignition nozzle 4 is tapered in the shape of a small diameter cylinder, and the foremost end has a relatively sharp rim in the shape of a cylinder.

Therefore, when the preceding unit 24 generates a high voltage, a discharge spark occurs between the circumferential edge and the circumferential edge of the inner flange at the lower end of the fixing ring 6.

An opening 4h is provided below the circumferential portion of the small diameter of the front end of the ignition nozzle 4.

The mixing pipe 5 has an inner flange for supporting the hole plate 10 in the center portion, and an air intake port 5h for sucking air thereon.

The hole plate 10, the washer 11, and the filter 12, which grind the holes 10h, are inserted into the mixing tube 5 from the lower opening in this order, and the flange tube 13 is the mixing tube 5 The plate 10, the washer 11 and the filter 12 are pressed against the inner flange of the mixing pipe 5 by being screwed into the lower opening.

The heat-resistant 0 ring 14 is attached to the side circumferential surface of the flange tube 13, which maintains the airtightness of the screw fitting portion between the mixing tube 5 and the flange tube 13.

In the flange tube 13, the front end of the stretchable synthetic resin tube 15 is pressed, and pressed against the inner wall of the flange tube 13 by the stretching force.

When the nozzle 20 is pulled upward and fuel gas comes out of the nozzle 20, it passes through the resin tube 15, and then the filter 12, the center hole of the washer 11 and the hole of the plate 10. It enters into the mixing pipe 5 through 10h, and then enters the ignition nozzle 4. As shown in FIG.

By the flow of this fuel gas, air is sucked into the inside of the pipe 5 through the air intake port 5h of the mixing pipe 5 and proceeds to the ignition nozzle 4 while mixing with the fuel gas.

The gas mixed with air and fuel gas, that is, mixed gas, exits from the opening 4h of the ignition nozzle 4 to the interior space of the ceramic cylinder 3 and then proceeds to the interior space of the fixing ring 6.

From the inner space of the ceramic barrel 3 to the inner space of the retaining ring 6, in the reed, the above-mentioned ignition spark is placed between the leading edge of the ignition nozzle 4 and the circumferential edge of the inner flange of the retaining ring 6. If this occurs, the mixed gas is ignited thereby to form a spark. The catalyst 7 is heated by this flame and burned hot. Since the catalyst 7 also has anti-inflammatory and discoloring effects, the flame above the catalyst is difficult to see with a blurred color, but when the front end of the cigarette is placed above the catalyst 7, , Ignite.

Since the combustion gas is mixed with air in the conductor cylinder 2, there is a flame, and the flame in the conductor cylinder 2 is hard to extinguish by the wind.

When a relatively strong wind enters the conductor cylinder 2 from the top of the catalyst 7, this flame is also temporarily turned off.

However, when the catalyst 7 is exothermic and this is in a high temperature state, when the mixed gas is contacted by its phase promoting action, the mixed gas becomes a flame.

Therefore, even if the flame goes out temporarily, another spark occurs.

Due to the combustion-promoting action of such a catalyst 7, the wind-resistant effect is higher than that in the case of simply having a cylinder.

The flame rises from the hexagonal opening 9h of the pressing ring 9 through the catalyst wire 7, which causes the catalyst wire 7 to be heated up and promotes combustion of the catalyst wire 7. By action, the flame becomes pale blue or transparent.

If you close the end of the cigarette above the opening 9h, it will catch fire.

When the catalyst wire 7 is heated, even if a strong wind enough to blow out the flame temporarily touches the opening 9h and the flame is extinguished, the flame is regenerated by the catalyst wire 7 portion when this wind passes. .

Therefore, there is also a wind-resistant effect against a relatively strong wind.

When the top cover 28 is covered, the nozzle 20 is lowered to stop the emission of fuel gas and the combustion is stopped.

Since the ceramic cylinder 3 is difficult to drill a screw hole, it is usually fixed to metal by forming a metal layer on the surface by plating or neutralization, and welding the metal to it. ) And the outer ring of the ceramic cylinder 3 are fastened to the ceramic cylinder 3 by the fixing ring 6.

Moreover, since this invention does not require plating and intermediate | middle stage, processing is easy.

Since the catalyst support ring (8) is tightened by the fixing ring (6) and the pressing ring (9) and fixedly attached to the support cylinder (2), the cleaning of the catalyst wire (7) around the ignition nozzle (4), etc. When the catalyst wire (7) needs to be removed, the pressing ring (9) can be removed from the support container (2), the catalyst support ring (8) can be removed, and the decomposition and cleaning without destroying the lighter, Repairs can be performed easily and simply.

As the electrode for discharging the high pressure of the piezoelectric unit 24, the ignition nozzle 4 and the fixing ring 6 are used as they are, and the connection between the ignition nozzle 4 and the piezoelectric unit 24 is simply a piezoelectric unit 24. Since the high pressure lead 24h of () is wound with the coil 24w and only the slave 5s of the ignition nozzle 4 is passed through the coil 24w, there is no need to use soldering or screws, Simple and sure.

As described above, according to the present invention, there is provided a gas combustion device having high water retention property (property to keep the flame) and high anti-off effect, and easy to supply high pressure electricity for gas ignition and simple anti-off gas burning. An apparatus is provided.
